Fig. 6: Water purification capacity by photocatalytic degradation.
From: Hierarchical optofluidic microreactor for water purification using an array of TiO2 nanostructures
a The MO degradation and b the SMX degradation of the TiO2 nanohelix-based microreactor. The error bars represent the standard deviations of three samples. c SEM images of polystyrene particles before and after photocatalytic degradation. d PS particle diameter distribution before and after degradation. The inset shows the average diameter of the particles. Scale bar: 200 nm.
